Virtualization technology has led to various products such as server, desktop, and application virtualization. These products are developed by different vendors, including Microsoft and VMware. Virtualization maximizes hardware utilization and offers benefits such as cost savings and efficient resource allocation.
There are many types of virtualization technology and, therefore, a number of different virtualization products. The concept of computer virtualization that began in the early 1960s led to the emergence of everything from virtual networks to virtual infrastructures. Among the most common products are solutions oriented towards servers, desktops and applications.
Server virtualization products are designed to create multiple virtual servers that emulate physical machines. This is made possible by creating individual operating system (OS) environments that are logically isolated from each other. Through the process of virtualization, a multitude of operating systems are able to run on a single physical machine simultaneously. The goal of server virtualization products is to maximize the utilization of the underlying hardware and its resources.
Desktop virtualization products use the client-server model to separate the desktop environment from the physical machine. This type of software provides the user with remote access to their PC, whether it is at home, in the office or in a data center. A virtualized desktop can be accessed from a variety of end-user devices, including thin clients, laptops, and PDAs. Desktop virtualization can make a PC accessible over any supporting network connection, on virtually any compatible device.
Application virtualization products isolate applications running on hardware from the operating system and from each other. These allow the deployment of a virtual environment, complete with registry keys, DLLs and frameworks, without the need to install additional applications or services on the host system. Application virtualization offers many benefits, including savings on software licensing costs, optimal resource allocation, and more efficient use of hardware. These products are used in fields such as e-commerce, online banking and supply chain management.
Virtualization products are developed by many different vendors. Two major providers are Microsoft® and VMware®. One of the most popular Microsoft® products is Microsoft Virtual Server®, a standalone virtual machine monitor (VMM) that aids in the creation of virtual machines on Windows XP®, Windows Vista® and Windows Server® operating systems. VMWare Server is just one of many in VMWare®’s broad portfolio of virtualization products. This software is known for its ability to run on the host operating system and in addition to the virtual machines running on the system.
As computing evolves, virtualization continues to advance. For years, this technology has enabled organizations and users to maximize their hardware while enjoying the optimal performance of their applications. Considering its prevalence in the IT world, the future introduction of more innovative virtualization products is very likely.
